There’s no difference.  I wouldn’t call Windows C++ WCHAR “UCS-2”, however if wc[0] = 0xD800 and wc[1] = 0xDC00, it’s going to act like a there’s a U+10000 character at wc[0], and wc[1] is going to be meaningless.  Which is exactly how JavaScript behaves today.  The JavaScript engines don’t care if it’s UCS-2 or UTF-16 because they aren’t doing anything meaningful with the difference, except not supporting native recognition of code points > 0x10000.
